How to Bleach Skin Spots
Age spots, melasma hyperpigmentation caused by pregnancy, scarring and freckles can all cause your skin to be darker in some spots than in others. Lightening or bleaching these spots can give your skin a more uniform appearance. Bear in mind that not all chemical bleaching agents are equal; the effectiveness of one formula may be better than another, and even the same product may give different results in two different people.
Wash your hands as well as the areas to be treated with warm water and soap before you apply the bleaching agent. Dry the affected area well with a towel before proceeding.
Test your bleaching cream or ointment on a small area of skin before treating the entire dark spot. Watch the test patch for a full day to be sure you are not allergic to the product. You may develop a red rash, itching or swelling if you have sensitivities to any of the drugs or other ingredients in the solution.
Apply a hydroquinone, kojic acid or glycolic acid-based bleaching agent to the hyperpigmented spot in the morning and at bedtime. According to the New Zealand Dermatological Society Incorporated's Dermnet NZ service, hydroquinone should be used for six months or less to avoid complications associated with long-term use, including slowed wound healing. Products containing other bleaching agents may be used for longer periods of time under the supervision of your doctor.
Rub the bleaching cream or ointment into your skin thoroughly so that it can penetrate to the lower layers of your dermis. Complete absorption of the product over time can fade the darkened spots, according to MayoClinic.com, but you may need to wait about a month before noticing results.
Wear sunscreen when you go outside to protect your skin, especially the age spots you're treating. New Zealand Dermatological Society Incorporated explains that your treatment method will not be as effective if you continue to overexpose your skin to the sun.
